FD-1/FD-1N
MONITOR
Pulse pick-up supply:
FD-1: Voltage: typ. 24 V DC; Current rating: max. 15 mA, protected against short circuit and
overload.
For external DC supply of the monitor via the terminals 1 and 2 the supply voltage of the
pulse pick-up corresponds to the DC supply voltage, less a low voltage for the short-circuit
protection.
For external supply of the monitor via the transformer or switched-mode power supply (ter-
minals 7 and 8) the supply voltage of the pulse pick-up corresponds to the rectified non-sta-
bilised output DC voltage of the internal transformer (nominal 24 V).
FD-1 N: Voltage: typ. 8.2 V DC
Reset inputs 1 and 2:
Reset for output 1 = terminal 17;
Reset for output 2 = terminal 18.
Current consumption: typ. 2.5 mA at 24 VDC.
Switch point for positive switching is specified >14 Volt.
Outputs
Output relay:
Switching capacity: max. 250V, 8 A.
The current has to be limited to these values by appropriate external measures.
Relay of output 1: terminals 13(COM), 14(NO), 15 (NC).
Relay of the output 2: terminals 19(COM), 20(NO), 21 (NC).
Rated for overvoltage category 2 and soiling degree 2.
All inputs and relay contacts are galvanically separated from supply voltages, tested to a
maximum of 250 V AC.
NOTE: If the relay is used to switch very low currents (e.g. plc inputs), considerable contact
resistance can arise, use the transistor outputs for these purposes. The life of the relay con-
tacts is considerably reduced by excess current or by the switching of unprotected inductive
loads.
Transistor outputs:
Positive switching, external supply at terminal 3.
Maximum voltage supplied: nom. 24V DC ± 20% incl. residual ripple, maximum switching
current: 15 mA
Depending on the function the voltage is switched to terminal 16 for output 1 and to ter-
minal 24 for output 2. They are protected against short circuits.
It is not allowed to apply external voltage to terminals 16 and 24!
Only for FD-1 N the voltage on terminal 3 is switched to terminal 4 and terminal 10
(fault outputs) depending on the function. The outputs are protected against short circuits.
